Laboratories are the source of all medical, pharmaceutical, chemical, and bioscientific research. Scientific English in the laboratory is a prerequisite for efficient communication and successful work. The corresponding terminology for lab facilities, equipment, tools, methods and technology is of equal importance as that of chemicals and safety-relevant issues. The Laboratory Dictionary contains some 12,500 terms in both languages (German - English) that are essential for living, surviving, and working in the lab. The Laboratory Dictionary will prove itself useful in working with manuals, catalogs, and operation instructions delivered with laboratory equipment as much as for reading and writing of scientific publications. The 2nd edition contains 1000 additional entries.
